I thought I saw someone working on a project that used LED strips with batteries at the Hive Space.
Does anyone have any information on this?
Thank you
I would like to more as well. I'm working on something similar -
strip in a tube and in various object manipulation/skill toy props.
I know Ryan was doing some stuff with LED strips, but I don’t think it was for use with batteries?
I had a white LED strip running on the electronics bench during the 6/18 meeting. Ian was also playing with some addressable RGB LED strand lights at the meeting table. Either of these might be what you're thinking of. We were using DC power supplies, but could easily run off batteries for short periods.
Many of us have spent time fiddling with such things. I have a strip version of Ian's strand lights in my Box Of Tricks in fact, which I usually have with me at the meetings. If you have specific questions, feel free to ask them on the mailing list or raise them during a Tuesday meeting. Someone will be happy to help.
My rig uses two 18650s in parallel and a cheap ebay DC-DC boost

All fits inside a 7/8" ID tube and allows me to do:

Demo is just an RGB roll, picture was taken with a long exposure plus
rear-sync flash. Flash fires just as the shutter is about to close,
freezing the light source. Friend of mine has the photographic
process for this nailed down.
Also, expanding on that, my ‘string of lights’ is currently sitting in my locker – if you want to experiment with them, let me know and I’ll be more than happy to let you borrow them (and the arduino that powers them) until you figure out what you’re doing.
